Learning New Things About mtDNA Inheritance from a Four-Year-Old Boy and a Tenacious Team of Scientists
We inherit our cells’ mitochondria from our mother. These energy-producing organelles are present in large numbers in most cells, meaning that cells can contain thousands of copies of the DNA associated with the mitochondria (mtDNA)—all passed on wholly from our mother. New evidence suggests, however, that this cannon principle of maternal-only inheritance of mtDNA might […]
